1. Determination of methanol residues in crude glycerol for animal feed by gas chromatography
ABSTRACT: Crude glycerol is a major by-product of biodiesel production and is an economical additive feed for ruminants. However, residual methanol in crude glycerol can be harmful to animal health. Several methods exist for quantifying methanol residues in biodiesel, yet few have been described that identify the methanol level in crude glycerol. We propose

2. Optimization of lipids production by Cryptococcus laurentii 11 using cheese whey with molasses
This study aimed the optimization of culture condition and composition for production of Cryptococcus laurentii 11 biomass and lipids in cheese whey medium supplemented with sugarcane molasses. The optimization of pH, fermentation time, and molasses concentration according to a full factorial statistical experimental design was followed by a Plackett-Burman

3. Processos de inovação tecnológica para a glicerina produzida no processo de obtenção de biodiesel no Brasil
Biodiesel is considered as a viable alternative to partially replace fossil fuels. The manufacture process of biodiesel produces approximately 10% glycerin, the main byproduct. Due to the growth of the biodiesel industry in Brazil and abroad, the high volumes of glycerin become a bottleneck in this chain, given that currently use the glycerin market serves a

4. Synthesis of biodiesel from transesterification os soybean oil by homogeneous and heterogeneous catalysis / Síntese de biodiesel a partir da transesterificação do óleo de soja por catálises homogênea e heterogênea
Biodiesel is defined as a mono alkyl ester of fatty acids of long chain derived from renewable sources such as vegetable oils and animal fats. Its importance is related to the use as an alternative fuel for diesel cycle engines. The biodiesel could be obtained by the transesterification reaction in which triacylglycerides (oil or grease) react with alcohol i

5. Enzymatic route selection for monoglyceride production using immobilized lipase on matrix obtained by sol-gel technique / Estratégias para desenvolvimento de um sistema operacional eficiente para a produção enzimática de monoglicerídeos
The objective of this project was to select the best enzymatic route to produce monoglycerides using lipase immobilized on matrix obtained by sol-gel technique, aiming to contribute for a better utilization of the glycerol generated as by-product in the biodiesel synthesis. For this purpose two methodologies were analyzed: (1) direct esterification of the gl

7. Análise de ecoeficiência: avaliação do desempenho econômico-ambiental do biodiesel e petrodiesel. / Eco-efficiency analysis: environmental-economic assessment of biodiesel and petrodiesel.
Biodiesel is the most likely alternative to petrodiesel. It is composed of methyl or ethyl esters from fatty acids, obtained by a transesterification reaction between any triglycerides and an alcohol with short chain, methanol or ethanol. It has almost the same properties of petrodiesel, but comparing with this, it can eliminate the sulfur oxides emissions a
